in order to store a password into device, the BCU Key feature needs to be used

BCU Key

if set: all devices of the project supporting this feature will be locked with the project's BCU Key during device download, the effected devices can afterwards only be read/modified by means of the BCU Key.

caution, use this feature with care and consequently:

ALL affected devices must be returned to the manufacturer if the BCU Key is lost or forgotten

it is highly recommended to update ALL devices whenever the BCU Key is changed

this setting is by default enabled and has the purpose to avoid possible incompatibility issues with ETS3 plug-ins

if set:

ETS3 plug-ins cannot use the full Group Address range

i.e. in the 3-level representation this range is limited to: 0/0/1 .. 15/7/255

if not set:

ETS3 plug-ins can use the full Group Address range

i.e. in the 3-level representation this means: 0/0/1 .. 31/7/255

Use slowed bus communication

if set:

all devices of the project will be programmed with standard frames (also the devices supporting long frames)

telegram throttling is enabled, which means that ETS will send out telegrams at a lower pace, i.e. a 150 ms delay between two telegrams will be used, this in order to support first generation products properly

if not set:

devices supporting extended frames will be programmed with extended frames, devices not supporting long frames will be programmed with standard frames

telegram throttling is not enabled, which means that ETS will send out telegrams without delay between two telegrams

Project Password details:

Set/change the project password

colors indicate password strength (Weak, Okay, Good, Very Good)

applied criteria:

minimum length = 8 characters (maximum = 20)

combinations

lower case characters (a,b,c...)

upper case characters (A,B,C...)

numbers (0,1,2,...)

special characters (#,!,/,...)

evident or recognizable patterns

sequences (not "ABCD1234" or "uuuuuu")

repetitions (not "AB12AB12")

Disable the project password

enter the current password and confirm under 'Delete Password'

Effects of the project password

not possible to open/edit the project without the password

the project is encrypted during project export; its data cannot be interpreted

Warning

there is no way to recover project data if its password is lost, not even by KNX Association

if the password is lost, the only option left is to delete the project

the password does not prevent project deletion; it 'only' protects the contents
